Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642822, here are decompositions:

3 + 8642819 = 8642822
61 + 8642761 = 8642822
241 + 8642581 = 8642822
313 + 8642509 = 8642822
373 + 8642449 = 8642822
439 + 8642383 = 8642822
541 + 8642281 = 8642822
1039 + 8641783 = 8642822

Showing the first eight; more decompositions exist.
